Abstract

The valve comprises a movable closure member and a seat in which the closure member is displaced relative to the seat for varying the gas flow through the valve. According to the invention, the process comprises causing the displacement of the movable closure member by means of a step-by-step motor as a function of the variation of the flow produced by each step according to the geometry of the valve, the type of flow employed and the pressure of the gas on the upstream and/or downstream side of the valve, and then producing a corresponding control signal for displacing in the desired direction the motor through the number of steps corresponding to the calculated flow, the displacement of the motor causing the correlative displacement of the movable closure member.
